Reinforcements added to pure AA5083 alloy are known to lower the overall weight while improving the strength of the Metal Matrix Composite (MMC). In this work, Silicon carbide (SiC) particles are added to pure AA5083 in varying quantities (3%, 5%, 7% and 10%), and tested to failure using tensile testing. The stress-strain behavior is decomposed into the elastic and plastic behavior and is validated using Finite Element (FE) modeling. The results exhibited an increase in ultimate tensile strength (UTS) of the MMC up to 5% of SiC. The formation of intermetallic compounds due to reactions at high concentrations of SiC resulted in debonding in the MMC and thus reduction in UTS. In this work, the response of the material between yield and complete failure is characterized using VOCE nonlinear model in FE analysis. It is observed that MMC with 5% SiC has shown maximum UTS (340.34 Mpa), while MMC with 10% SiC content has resulted in the most ductility (27% plastic strain) of all the compositions. Further, MMC with 7% SiC has highest saturation stress (R 0 = 653.09 Mpa) and lowest ductility, while MMC with 10% SiC has lowest saturation stress (R 0 = 115.57 Mpa) and highest ductility.

“…However, based on the final length of the specimens, a significant elongation can be observed though no necking has occurred. The complete stress strain curves of the tests are published in KUMAR et al [31]. Once the experimental data is obtained, further analysis is performed as explained in the subsequent sections.…”

“…In recent years, the utilization of FA reinforcements is due to their low cost and availability as a waste by product in thermal power plants. More so, electromagnetic shielding effect of the Al-MMC was reported to have remarkably improved by utilizing FA reinforcements [40,41,45,46].…”

Research Summary on the Processing, Mechanical and Tribological Properties of Aluminium Matrix Composites as Effected by Fly Ash Reinforcement

Fly ash is the main waste as a result of combustion in coal fired power plants. It represents about 40% of the wastes of coal combustion products (fly ash, boiler ash, flue gas desulphurization gypsum and bottom ash). Currently, coal waste is not fully utilized and waste disposal remains a serious concern despite tremendous global efforts in reducing fossil fuel dependency and shifting to sustainable energy sources. Owing to that, employment of fly ash as reinforcement particles in metallic matrix composites are gaining momentum as part of recycling effort and also as a means to improve the specifications of the materials that are added to it to form composite materials. Many studies have been done on fly ash to study composite materials wear characteristics including the effects of fly ash content, applied load, and sliding velocity. Here, particular attention is given to studies carried out on the influence FA content on physical, mechanical, and the thermal behavior of Aluminium-FA composites. Considerable changes in these properties are seen by fly ash refinement with limited size and weight fraction. The advantage of fly ash addition results in low density of composites materials, improvement of strength, and hardness. It further reduces the thermal expansion coefficient and improve wear resistance.
